As you can see in the Picture below, the switch does not really matter in this case. The switch model is a HP V1910-24G (Software Version 5.20).Ģ. You capture packets for WAN1 and LAN interfaces?ġ. You draw detailed topology with IP addresses on it? You check if you activated Loopguard in the switch? The switch’s model name and firmware version? Has anyone an idea why the WAN interface goes down? This way I can create firewall rules for those VM's. The target of the whole setup is, that I can create 2 VM's on the server, each of them would be mapped to a dedicated interface of the server which is connected to a dedicated interface on the firewall. For port 4 and 5 I used one able for each port directly without a switch inbetween. I also did a ping directly on the firewall from the CLI. If I connect the server to both ports 4 and 5, then I loose the internet connection compleatly. As soon as I connect the server to one of the Ports 4 or 5 I have some package loss if I ping the internet. Port 4 and 5 are configured internal, and are mapped to their own zone on the firewall. Two additional ports on this server could be used to connect to the firewall.

One port is connected to the switch, so that the server has internet access. Now i would like to connect Port 4 and Port 5 of the firewall to a server used for Virtual Machines (HyperV). This is working so far well and everyone has internet access. Port 3 is connected to our LAN (configured as internal) over a switch. Port 2 is used as a WAN port (configured as external), PPP is not configured, since that is done on a router managed by our provider. We have a zyxel usg flex 500 with 8 ports (one fiber, 7 RJ45).
